What grade point average do you need to become an astronomer?
I just saw something cool in the sky. It was moving and looked like a string of lights in the sky and suddenly they were gone. There were 3 minutes between the two pictures. Can anyone tell me what it is?
Hello, I have a purely hypothetical question: Suppose we have a 1m^3 cube with perfect insulation containing water at 21°C. This cube floats in space. Now the insulation disappears all at once and the water contained within it would be completely exposed to the vacuum of space. a. How long would it take for this…
Good day, I am currently preparing a lecture on cosmic speeds, and the following applies: first cosmic speed: Centripetal force (here: gravitational force) = centrifugal force second cosmic velocity: kinetic energy = binding energy But why is binding energy used here instead of gravitational force, since gravitational force also acts on the object?

A program like downloading “Stellarium” is of course optimal. For an overview, however, a page like

click the sky preview on the top left.
Here is the Stellarium

Thanks for the star!
Internet star cards are usually only simple and useless. I would recommend you the Stellarium program with which you can use much more than Internet cards. You can watch the sky from any place in the world (also from other points in the solar system), at any time in the next/last 100,000 years and also zoom in to see what the objects look like in the telescope. This is a great program to recommend!

From the I-Net you can download free “The Planetarium 1900-2100”, there is everything you need.Great M.
